Lamentations 3:29

Now we [all] know that everything the law says applies to those who are under [obligation to obey] that law, [Note: Here "the law" appears to refer to the Old Testament Scriptures generally, since Psalms and Isaiah are quoted. See verses 10-18]. This is so that the mouth of every objector may be stopped [i.e., from making excuses for his sin], and thereby bring the entire world under God's judgment [i.e., both Jews and Gentiles].

I will get up and go to my father and say to him, Father, I have sinned against [the God of] heaven and against you.

But the tax collector stood at a distance [i.e., inconspicuously] and would not even look up to heaven, but struck his chest [i.e., in remorse], saying, 'God, [please] have mercy on a sinner like me.'
